# ip 库的处理
|
|
|
|
## 机制
|
|
1. SamWaf为了轻量化内置了ip2region.xdb。
|
|
2. 遇到识别不准的问题就得自己构建放在 data/ip2region.xdb,重启SamWaf就可以了。
|
|
|
|
## 如何生成 ip2region.xdb
|
|
这里使用 Ip2region(狮子的魂)。为了方便测试使用，fork了一份，生成了windows和linux的可执行文件。
|
|
|
|
https://github.com/samwafgo/ip2region/releases
|
|
|
|
|
|
|
|
- 1.编辑
|
|
|
|
下载一份原始ip数据
|
|
|
|
https://github.com/lionsoul2014/ip2region/blob/master/data/ip.merge.txt
|
|
|
|
|
|
```
|
|
xdb_maker.exe edit --src=./ip.merge.txt
|
|
|
|
```
|
|
|
|
打开ip.merge.txt ，我们拿8.8.8.8来测试。把这个复制出来：8.8.8.0|8.8.8.255|美国|0|0|0|Level3 ，稍加改动
|
|
|
|
```
|
|
|
|
put 8.8.8.0|8.8.8.255|美国测试|0|0|0|Level3
|
|
|
|
```
|
|
|
|
- 2.保存
|
|
|
|
```
|
|
save
|
|
```
|
|
|
|
|
|
退出xdb_maker
|
|
|
|
```
|
|
|
|
quit
|
|
|
|
```
|
|
|
|
- 3.最后生成db文件
|
|
|
|
```
|
|
xdb_maker.exe gen --src=./ip.merge.txt --dst=./ip2region.xdb
|
|
```
|
|
|
|
这个时候会花几分钟时候构建，出现这个就OK了，可以复制ip2region.xdb到data下了
|
|
|
|
```
|
|
|
|
2024/10/10 16:17:08 maker.go:283: try to write the vector index block ...
|
|
2024/10/10 16:17:08 maker.go:294: try to write the segment index ptr ...
|
|
2024/10/10 16:17:08 maker.go:307: write done, dataBlocks: 13828, indexBlocks: (683843, 720464), indexPtr: (983612, 11070094)
|
|
2024/10/10 16:17:08 main.go:112: Done, elapsed: 2m36.219498s
|
|
|
|
```
|
|
|
|
- 4.【可选】 批量测试是否正常：
|
|
会挺慢几分钟
|
|
```
|
|
|
|
xdb_maker.exe bench --db=./ip2region.xdb --src=./ip.merge.txt
|
|
|
|
```
|
|
|
|
|
|
```
|
|
|-try to bench ip '224.0.0.0' ... --[Ok]
|
|
|-try to bench ip '247.255.255.255' ... --[Ok]
|
|
|-try to bench ip '239.255.255.255' ... --[Ok]
|
|
|-try to bench ip '247.255.255.255' ... --[Ok]
|
|
|-try to bench ip '255.255.255.255' ... --[Ok]
|
|
Bench finished, {count: 3419215, failed: 0, took: 3m48.3903262s}
|
|
```
|
|
|
|
|
|
## 查询相关
|
|
|
|
- 1.替换后 通过日志查看
|
|
|
|
|
|
|
|
|
|
- 2.测试数据库查询是否正常，也可以用工具先看看：
|
|
|
|
xdb_searcher.exe search --db=./ip2region.xdb
|
|
|
|
```
|
|
|
|
iptest>xdb_searcher.exe search --db=./ip2region.xdb
|
|
ip2region xdb searcher test program, cachePolicy: vectorIndex
|
|
type 'quit' to exit
|
|
ip2region>> 8.8.8.8
|
|
[0;32m{region: 美国测试|0|0|0|Level3, ioCount: 7, took: 617.7µs}[0m
|
|
ip2region>> quit
|
|
searcher test program exited, thanks for trying
|
|
|
|
``` |
